Competing electronic orders on kagome lattices at van Hove filling

Abstract: The electronic orders in Hubbard models on a Kagome lattice at van Hove filling are of intense current interest and debate. We study this issue using the singular-mode functional renormalization group theory. We discover a rich variety of electronic instabilities under short range interactions. With increasing on-site repulsion U , the system develops successively ferromagnetism, intra unitcell antiferromagnetism, and charge bond order. With nearest-neighbor Coulomb interaction V alone (U = 0), the system deve… Show more

“…[9,24] The FRG is particularly promising to address the multi-scale energy issues in ruthenates. In recent years the FRG has been expanded to treat 2D multiorbital systems such as the iron pnictides and selenides [25][26][27] and candidate models of topological superconductors with or without time-reversal symmetry [28][29][30][31][32]. In addition to addressing the pairing symmetry and energy scale, FRG gives information on the relative strength and wavevector of competing orders in the particle-hole chan-…”

“…Either way, the computational effort of fRG studies may be lowered considerably, in particular for two-dimensional systems with a sixfold symmetry, such as multilayer graphene [5][6][7] and electrons on a Kagome lattice [15,19]. Currently, two of us are preparing a publication on an fRG study of the Emery model with non-zero oxygen-oxygen hopping and at weak coupling.…”

“…(For other reasons, fRG calculations in the orbital language can still be viable and maybe even preferable in some cases, cf. for example, [16,18,19].) This can be accomplished by a unitary transformation, u(k), of the orbitor, Ψ a (k), in the orbital picture to the band picture with pseudo-spinors:…”
